چکیده انگلیسی
Structural properties of Fe60Cr40 powders prepared by mechanical alloying in different atmosphere were investigated by using X-ray diffraction and 57Fe Mössbauer spectrum. The results show the formation of BCC paramagnetic structure when the sample sealed under Argon milled for 85Â h. While in vacuum of 6Ã10â2 Pa, the BCC magnetic disordered solid solution is obtained for milled 45Â h and more. The hyperfine filed distributions of Fe60Cr40 milled for 85Â h in Argon is comprised of the crystalline grains and the disordered grain boundaries. Those of Fe60Cr40 milled for 85Â h in vacuum indicate the formation of disordered alloys with nanoscale heterogeneous structures and the homogenization still proceed for a long milling time.
